javascript - 获取本周和下一周的日期

Question

我想要一个包含本周和下周日期的数组。 我尝试用 for 循环和 while 循环来实现这个，但目前没有成功

getTwoWeeks = () => {

    let twoWeeks = [];
    let days = 14;
    let today = new Date;
    let calcFirst = today.getDate() - today.getDay();
    let firstDayOfWeek = new Date(today.setDate(calcFirst));

    for(let i=0; i<days; i++) {
        twoWeeks.push( new Date(today.setDate(firstDayOfWeek + days[i])) )
    }

    console.log('twoWeeks===',twoWeeks )
}

Answer 1

您可以先计算本周的星期一，然后从那里迭代到 14 天。

const today = new Date();
const dayOfWeek = today.getDay();
const lastMonday = new Date(today.setDate(today.getDate() + (dayOfWeek * -1 + 1)));

for (let i = 1, d = lastMonday; i <= 14; i++, d.setDate(d.getDate() + 1)) {
  console.log(new Date(d));
}
